OPERATION 1448 PLUS
NOTE:
Leave a small head of asphalt at the
leading edge of the screed while waiting for
the next load of asphalt. If the wait is longer
than 10 to 15 minutes, pave 12 to 18 inches
(300-450 mm) and leave a small head of
asphalt at the leading edge of the screed.
Repeat this every 10 to 15 minutes using
asphalt remaining in the hopper until the next
load arrives.
7. After the hopper is fully loaded, have the truck
driver lower the dump body to stop the flow of
asphalt to the paver. At the same time, move
the hopper control lever to the "up" position.
This raises the hopper and avoids asphalt spills
from the front of the hopper.
8. Have the truck driver move forward to the next
reloading place to reload the paver. The next
reloading place may be in front of the paver at
a location where the paver operator expects the
hopper to be emptied, or another location on
the jobsite.
PRECAUTIONS WHILE PAVING
The right side control levers for auger, extension,
travel and hopper modes require a two-person
operation. The two-person operation helps avoid
making "blind" joints and reduces cycle time when
paving in two directions.
Only operate the screed vibrator when the paver is
moving to avoid compaction in the mat when the
paver is stopped.
Do not raise the hopper against the truck frame or
dump body.
When pushing a truck on level ground, the truck
should not be in gear and the truck brakes should
not be held. The paver should not push a truck with
the brakes on.
Only use the two independently-operated augers
when the extensions are out, and then only occa-
sionally. The augers are only used for keeping the
extended area fully charged with asphalt.
NOTE:
DO NOT leave the augers operating
continuously unless required!
If the hopper is loaded and the operator wants to
close the flow gates (to transport material to an
area inaccessible to the truck, reposition the paver
for the next pass, etc.), complete the following
steps:
1. Lower the hopper as low as possible without
spilling asphalt. This decreases the weight
being lifted by each flow gate.
2. Close both flow gates.
3. Close the screed extensions.
When paving uphill, lower the hopper as needed.
This places more weight directly over the tracks to
increase traction.
Handling Asphalt Spills
IMPORTANT:
Remove all asphalt spills from
the path of the paver tracks to prevent loose
asphalt from getting into the tracks or building
up on the sprockets.
WARNING
Do not attempt to move hot asphalt mix with
your hands or feet. Contact can cause serious
skin burns!
Complete the following steps if the asphalt truck
moves away from the paver and spills asphalt in
front of the paver:
1. Stop the paver.
2. Lower the hopper as low as possible without
spilling asphalt. This decreases the weight
being lifted by the flow gates.
3. Close both flow gates.
4. Windrow spilled asphalt to the center and in
front of the paver. Be sure that the asphalt is
removed from the path of the paver tracks.
5. Move the speed control lever "forward,"
and continue to pave with asphalt gravity fed
from the hopper. As the asphalt head from the
hopper begins to run thin, the windrow asphalt
should be at the leading edge of the screed.
If this is the case, continue to pave using the
windrow asphalt and open both flow gates
